近年来,我们感到逆行性牙髓炎的发病率逐渐增加,在治疗上也渐形成具有一定模式的程序和方法,现报告我们的作法和体会。 共治疗89人103个牙(男50人55牙,女39人48牙),年龄27～69岁。患病率随年龄增加而上升,前牙以中切牙患病率最高,侧切牙次之,尖牙最低;后牙以第一磨牙患病率最高,第二磨牙次之,第三磨牙较少,这也许是因部分患者第三磨牙缺失之故。
In recent years, we have seen a gradual increase in the incidence of retrogressive pulpitis. As a result, we have gradually developed procedures and methods that have some patterns in treatment. We report our practices and experiences. A total of 89 89 teeth (male 50 55 teeth, female 39 48 teeth), aged 27 to 69 years. Prevalence increased with age, the highest prevalence of anterior teeth in the incisors, lateral incisors followed, the canine lowest; posterior teeth to the highest prevalence of the first molars, the second molars, the third molars than the third molars Less, this may be due to the lack of third molars in some patients.
